This invention relates to improvements in ear doors.

One object of the invention is to provide a car door of the doubleoutside sliding type and more particularly such a door for ox cars usedin the transporting of automobiles, furniture and other articles oflarge size.

A specific object of the invention is to. provide adouble door composedof sheet metal, and wherein maximum strength against thrust in everydirection for a given weight is obtained.

Another specific object of the invention is to provide a double doorwherein the secondary or auxiliary door has the front edge thereof soconstructed and braced, in' combination with inexpensive fixtures usedtherewith, as to provide unusual strength against lateral thrusts.

Another specific object of the invention is to provide novel andeflicient means, particularly adaptable to steel sheet metalconstruction, for locking the secondary or auxiliary.

door in its so-called closed position.

clearly appear from the description and claims hereinafter following. v

Figanother embodiment of myimprovements. Figure 13 is an outside elevational view of the frontlower corner of the door illustratedin Figure 12. And Figure 14 is avertical sectional view-corresponding to the sect ion line 1414 ofFigure 13. Referrm ,first to the construction illustrated in igures 1 to11 inclusive, 20 indicates the usual side plate of a box car, 21 theside facia board, 22 the door lintel, 23 the floor boards, 24 thethreshold plate, 25 a car side sill, 26 a supporting block for extendedfloor boards and 27 one of the door posts or jams, the one at the rearedge of the auxiliary door, it being understood that there will be asimilar post at the opposite side of the large door opening.

In the arrangement shown, two sliding outside doors are employed, onewhich may be termed the main door and designated iary door, which isindicated by the reference character B. In the form shown in Figures 1to 11, the doors are of the top hung type,

each preferably being provided with a pair of roller carrying brackets28 -28, each bracket having a roller'29 which rides upon a Z-bar track30, the brackets being so formed that they clear the outermost flange ofthe track and the door having its upper edge extending inside of theoutermost trackflange, so as to thereby prevent the door from movingoutwardl' with respect to the track. The main door is composed of sheetmetal throughout, the same preferably being formed with vertical andhorizontal corrugations and multiple-ply edges, as described in inPatent No. 1,315,537. The secondary door is also formed of sheet metalof a construction similar, ingreater-part, to the main door A, but a pthe side wall of the car and having a double beveled or cam surface 35.The rear lower corner of the door B preferably has secured thereto adouble-wedge casting of the form best indicated in Fi re 7 andreferenced 36 'so that the same wi l wedge against the respective guidebrackets carried by the car body. At the front lower cornersjl'of'eachof the doors A and B, that is, the two meeting corners as illustrated inFigure 1, each door is preferably rovided with a 'single wedge bracket37 of t he type indicated in Figure 8. When the two doors A and B areclosed, as

shown in Figure 1, the respective brackets 37 of sheet metal panelssuitably united along sheet of the door, the latter being then corrutheir meeting edges and forming the mam gated so as to provide arear'vertical ed e corrugation 38, a lower horizontally exten ingcorrugation 39, a partial vertical corrugation 40 at'the front edge ofthe door, and a series of horizontally extending corrugations 41 withinthe three-edge corrugations referred to the corrugations 41 merging attheir ends with the vertical corru ations 38 and 40. At

the bottom of the door a plate 42 is riveted or otherwise rigidlysecured to the main sheet,

said plate 42 bridging the corrugation 39 as shown in Figure 3 andproviding a'doubleply lower edge. imilarly anotherstri 43 is employed atthe rear edge of the door on the inner side of the main sheet, the strip43 bridging the verticalcorrugation 38- and rive eted to themain sheeton opposite sides of the .8 said corrugation 38, said strip 43'beingpref- .3

erably extended at its rear edge and bent to hook-shape as indicated at44, 'so as to engage over the projecting ed e 45 of 'a wear plate 46applied to the exposed faces of the post 27.

this manner, a spark and weather seal is obtained for the rear edge ofthe door B. At the front edge of-the door B, a special construction 'ofgreat strength is employed. The same comprises the extended flange 40 ofthe partial corrugation 40, made b the main sheet ofthe door, aisecondstrip 4 and v a section 48 of angle bar, as best 'shown in m Figure 2.The angle bar 48 has an outer relatively narrow flange 49 extendingparallel to the side wall of the car and to which is riveted orotherwise rigidly secured, the extension 40?. The angle section 48 hasan elongated leg 50 extended transversel of the caran'dto which one edeof the str1p 47 is riveted or otherwise rigi y secured, as mdicated at51, it bein observedithat the other edge of the strip'4 is secured tothe'main sheet of the door at a point inwardly of the corrugation 40, asindicated at 52 and that the strip 47 is extended angularly inwardlyfrom the main plane' of the door. As best shown in Figures 3 and 4, theflange 49 of the- .aalgle section 48 extends for the full height of thedoor B, but the leg 50 terminates a short distance below the lintel anda short distance above the threshold. The lower horizontal wedge pocketcastin strip 42 and the upper corresponding strip 142, which bridges thetop. horizontal edge corrugation 139, are extended, as indicated at 53in FigureQ, and-thence bent at-right angles, as indicated at 54 andangle section 48.

t0 the 2 'ZVVith the construction described, it be sist bending fromthrusts imparted parallel to the side wall of the ear-and race themember '48 a ainst rotation aboutits longitudinal axis, an also toresist bending or exerted inwardly against the door It'w'ill be notedalso that the double-ply edge overhangs the front edge of the main doorA and is therebyadapted to provide a weather or spark sealatlthemeetingfedges of the two doors. I elongated le 50 of the angle sectionThe 48' provides a suite. le support for a heavy wood nailing block 55,which may be bolted to'the angle section, the inner faceofthen'ailing-block '55 bein in line with the inner face of the post 27 rethe auxiliary door B is not required and-when it maybe left for aconsiderable time in its closed position, the door'Bmaybe "locked insuch closed position and boards nailed to the post 27 and the nailingblock 55 to continue the inner-sheathing 56'of thecar. f To revent,thefront ed le oi theilo'orf rom in spr outwa emp oy t e followingfixtu l efi. Partial? countersunk within the lintel and partia ycountersunk withinthe threshold and anchored by bolts 57 -.'-57 arewedged pocket castings designated generally by the reference characterC. Each C, as best shown in Figures 3', 4, 5 and 9, as a verticallyextending loop-shaped flange 58 with a-tapered en.- trance, each loopbeing opened toward the post 27. 'Cooperable with the. loop-wedging withbrackets 60-60 secured to the top and flanges 58' are heavy lugs 59formed integral bottom, respectively, ofthe angle section 48. With thisconstruction, the front edge of the door B is properlyrg-uided as thedoor is moved to its closed position and, wzhenthe lugs 59 are properlywedged Within thefiamges 58, outward movement or springing .cfthe frontedge of the door B is 1prevented.

To lock the door B hits 0- osed position, I employ the following means,as best illustrated in Figures 2, lOand 11. Extending horizontallythrough the post 27 is a long arm .61 of 'a U-shaped bolt, the short arm62 thereof being extended back partially into the post 27 and leavingthe loop proper 63 of the bolt spaced away from the face of the post. Onthe lower or elongated arm 61 of the U-bolt, is pivoted a lock lever 64having an offset handle (Sh/and 'an arcuate projection 66 of T cross;stion. The projection 66 is adapted to swing within a corresponds inglyT-slotted casting 67, mounted within one of the horizontal corrugations41 of the door B so as to lie totally outside of the inner main plane ofthe door, as best illustrated in Figure 11. When the lever 64 is in-theposi-- tion shown in Figure 11, it is evident that the door B will beprevented from movement in an opening direction and also, when the lever64: is moved from engagement with the cooperating member 67 of the door,the latter may be moved to its open position without any interference.To hold thelever 64 in its locked position, the lever is provided with ashort arm above its pivotal point, to which is pivotally connected ahook latch 69 adapted to take over the short arm 62 of the U-bolt, asshown best in Figure 11. The lever 64 is released by disengaging thelatch 69 from the U-bolt as will be understood by those skilled in theart.

Referring next to the construction illustrated in Figures 12, 13 and'14.The structural features of the doors are substantially the same as thoseillustrated in the figures previously described, except for the s ecificdifferences hereinafter described. 11 the arran'gement shown in Fi ures12 to 14, the door is of thevso-called ottom hung type with thesupporting rollers 129 ridin upon a channel shaped track 130 supportefrom suitable brackets secured to the side sill. The top edge of thedoor is guided beneath a longitudinally extending, approximately Z-sec-'tioned stri 70, secured to'the outer de end- .ing flange 71 of. a Z-bar72. Along the ower edge of the door, is provided a Z-bar 73 havingdepending flange 7 4 engaging'behind the channel track 130 so as torevent the bottom edge 'of the door from ing sprung outwardly. v Toadequately support;each of therollers 129 on a sheet metal door of thepreferred type, I employ the following arrangement.

t each corner where a roller is rovided, a

portion 75 of the mainv sheet 0 the door, which would ordinarily form acontinuation of the lower horizontal edge corru 'ation 76 is extendedvertically in line with most plane of the door and spaced from there-inforcing strip 77, which is secured to the bottom edge of the door,as best shown-in Figure 1-1. To brace the vertical portion 75 of thesheet metal, I secure beneath. it, an extra strip 78 having flanges 9 ateach end-secared to the strip 77 andja vertical longitudi 'na'llyextending -'seetion .80, immediately beneath the plate portion 75. Theextra plate 78 and p0rtion"7 jam in turn braced or reinthe outer-- :i aM t 1 1M1 9 ends is supported by the three plates 81, 75 and 80 at oneof its ends and "by the strip 77 and Z-bar 73 at its other end, saidjournal 70 82 having the roller 129 rotatably mounted thereon. With thisarrangement, I provide the necessary strength against crushing orcollapse of the parts from vertical loads or thrusts and alsoagainstlateral thrusts while maintaining the weight at a minimum.

I have herein shown and described what I now consider the preferredmanner of carrying indentations, said door including portions divergingoutwardly, and a member having a portion arranged substantially normalto the main plane of said door and connecting with the spaced endportions of said diverging portions to provide one edge thereof ofapproximately triangular tubular cross-section.
